Application med May 7, 1930. serial No.` 450,526.

This invention relates to an apparatus for cleaning boiler tubes and, inview of the fact p that this work, when manually performed is dirty andtroublesome, the present invention E has as its primary object toprovide an apparatus whereby the tubes of a boiler may be thoroughlycleansed and any accumulations and the accumulations disposed ot in amanner to eilect their complete removal from the v tub es.

Another object of the invention is to provide'an apparatuswhich may bereadily and l quickly applied and removed from a boiler in preventingleakage.

position to flush the tubes thereoil and with out any likelihood ofleakage and without the necessity ot employing mechanical means for`This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafterl fully described, illustrated in the accompanying drawings,and specically pointed out inthe appended claim, it being understood ofcourse that minor changes may be made so long as they fall within thescope of the claim. p

ln describing my invention in detail, refen ence will be had to theaccompanying drawings, wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a view partly in side elevation and partlyin section, illustratingthe apparatus embodying the invention temporarily installed upon atubeboiler.

Figure 2 is a detail vertical sectional view through one unit of thedevice. Y

Figure 3 is a similar view through the other unit.

In the drawings and more particularly in Figure 1, the numeral 1indicates two of the tubes of a tube boiler and the numeral 2, one ofthe boiler heads in which the ends of the tubes are mounted, and thenumeral 3 indicates one unit of the apparatus, which unit is designedfor the injection ot compressed air port Gand a iange 7 surrounds thisport and 'a `washer 8ot rubber or other suitable packing material isapplied to the face ot this washer. Opposite the port 6, the body isprovided witli a seat 9 of nearly semi-spherical contour to accommodateone side ot a ball 10, and a cap member 11 is hinged as at 12 upon adownwardly and rearwardly curving spout 13, which leads from the lowerside of the body 4 and this cap `11 is formed with an i' opening 14, thewall oi' which is adapted to embrace the ball 10 when the cap member isin the closing positionshownin Figure 2 of the dra-wings, a locking link15 being pivotally mounted as at 16 upon the tree or upper Aside of thecap member 11 and engageable with a 'hooked shaped lug 17 upon the upperside of the body 4. A compressed air conducting pipe 18 is led throughthe spherical the port 6 and axially through a funnel 19 which has athreadedneck 20 fitted in the end of the said bore 6.

The pipe 18 at its other end is connected by a coupling 20, inwhich ismounted a manually adjustable cut-oli valve 21 with a pipe 22 which willpresently be again referred to.

Another unit for delivering air under pressure into another one of thetubes of the boiler is indicated in general by the numeral 23 and thisunit comprises a hollow body 24 having a branch 25 into which isthreaded one end of a pipe-26 which pipe extends into the boiler tube tobe supplied with compressed 'r air. The body 24 further comprises anupwardly extending branch 27 and this branch is iitted into the lowerend of a cut-ofi1 valve casing 28 and a pipe 29 is connected to theupper branch of the valve casing and likewise by a coupling 8() to thebranch 13 of the body 4 of the unit 8. The body 24 of the unit 23 isfurther provided with a horizontally extending nipple 31 which isinteriorly threaded and a nozzle 32 is fitted into this nipple and hasits tapered delivery end projecting into the body 24 and presentedtoward the intake end oi the tube 26. The coupling 33 connects thenozzle with the pipe 34 leading to a T-union 35 to the upper branch orball head 10 and this pipe extends through F lio of which the pipe 22,previously described, is connected.

This apparatus is a sanitary flue cleaner which is operated bycompressed air to create 5 force and suction drafts through the flues.The blast of air passing through the pipe 26 is passed under the dirtand cinders in the flue and carries the same towards the smoke boX ofthe locomotive (not shown). The

blast of air which enters the body 24 through the nozzles 32 creates areturn suction draft through the pipe 29 and air conducting pipe 18 andthe flange 7 closes one end of the flue whereby the dirt and cinderscannot reach the operator. The device is provided With a handle so thatit may be readily removed from the ilues of one locomotive and appliedto the lues of another.

20 A boiler liue cleaning apparatus comprising a hello7 body having apassageway therethrough, a funnel extending from one end of saidpassageway, a member mounted for universal movement opposite the innerend of the funnel, a compressed air supply pipe supported by said memberand extending axially within the funnel and beyond the outer end thereofand slidable relatively to said universally mounted member, a packingelement constructed to surround the inner end of a flue to be cleaned, abranch outlet leading from the bottom of the body, a second hollow bodyhaving forwardly, rearwardly and upwardly extending branches, a deliverypipe leading from the forwardly extending branch of said body to extendinto a liue below the first mentioned iue, a pipe extending between andconnecting the said branch outlet of the first mentioned body and theup- 40 wardly extending branch of the second mentioned body, a manuallyoperable cut-oil valve in said pipe, a nozzle in the rearwardlyextending branch of the last mentioned body and so positioned relativeto the forwardly extending branch as to create a reduction of pressurewithin the body, and a pipe connecting the said nozzle with thecompressed air supply pipe.

In testimony whereof I aflix my signature 5o PATSY LEONE.
